Uburyo bwo gukuramo imiti
Imyunyungugu ya karuboni ya dioxyde de chimique ikoresha uburyo bwa chimique hagati ya reagent ya chimique na dioxyde de carbone kugirango itandukane karuboni na gaze ya flue. Ifata CO2 ikoresha umutungo wa reagent zimwe na zimwe kugirango zifate hamwe na CO2 kugirango zivemo ibice. Irakwiriye gukoreshwa hamwe nubushyuhe buke bwa CO2 / igitutu cyigice, nko gufata gaze ya flu mu makara - amashanyarazi, amashanyarazi ya sima, ninganda zibyuma. Ubu buryo burakuze, hamwe ninganda zihari, nubwo igipimo cyibikoresho ari gito.
Uburyo bwo gukuramo umubiri
Gufata kwifata bifashisha umutungo ibintu bimwe na bimwe bifata umubiri bifite imbaraga nyinshi zo gukomera kuri dioxyde de carbone kuruta ibindi bice bigize gaze ya flue kugirango igere ku gutandukanya dioxyde de carbone nibindi bice. Uburyo bwo gufata ukoresheje reagent zifatika zigizwe mubyiciro bibiri: imwe ikoresha polyethylene glycol dimethyl ether nka reagent yo gufata, hamwe nibikorwa bisanzwe birimo inzira ya Selexol yatunganijwe na Union Carbide hamwe na NHD byakozwe na Nanjing Chemical Industry Institute Institute mu gihugu cyanjye; ubundi ikoresha methanol nka reagent yo gufata, hamwe nibikorwa bisanzwe ni Rectisol yo hasi - uburyo bwo gukaraba methanol yo gukaraba hamwe na Linde na Lurgi mubudage.
Absorption ya fiziki
Usibye uburyo bwo gufata imiti gusa nuburyo bwo gufata umubiri, ibigo bimwe byateje imbere uburyo bwo gufata hakoreshejwe imiti ivanze ihuza imiti niyumubiri. Ibi bifashisha ibyiza byuburyo bwombi kandi bizwi nko gufata umubiri wa fiziki.
Gufata Ubuhanga
A. Ikoreshwa rya tekinoroji yo gutandukanya
Ikoreshwa rya tekinoroji ya Adsorption ikoresha itandukaniro mugukurura hagati yibikorwa bikora hejuru ya adsorbent hamwe na molekile zitandukanye za gaz kugirango zitandukanye ibice bya gaze. Ubushobozi bwo gukoresha gaze ya adsorbent mubusanzwe bifitanye isano nubuso bwihariye; nini ubuso bwihariye, nubushobozi bwo gukoresha gaze. Kubwibyo, adsorbents muri rusange ni ibikoresho byoroshye. Ibisanzwe bikoreshwa muri adsorbents harimo molekile ya molekile, karubone ikora, gelika silika, hamwe na alumina ikora, cyangwa guhuza amatangazo abiri cyangwa menshi. Ubushakashatsi bwerekana ko bitewe n’imiterere yihariye ya karuboni ya dioxyde de molekuline yimiterere ya polarite hamwe na polarite, adsorbents nyinshi zifite ubushobozi bwo kwinjiza dioxyde de carbone kurusha iyindi myuka nka metani, monoxyde de carbone, hydrogen, na azote. Kubwibyo, amatangazo menshi arashobora gukoreshwa mugutandukanya karuboni ya dioxyde.
B. Ikoranabuhanga ryo Gutandukanya Adsorption
Gutandukanya Membrane ni uburyo bwo gufata karuboni ya dioxyde ikoresha igipimo gitandukanye cyo kwinjiza ibintu bitandukanye bya gaze mubikoresho bimwe na bimwe bya membrane. Intandaro yubuhanga bwo gutandukanya membrane ni ukumenya ibikoresho bya membrane bifite uburyo bwo guhitamo ibintu bitandukanye bya gaze; ibi akenshi ni kimwe cya kabiri - cyoroshye, kitari -. Umwuka wa gazi muri membrane ukurikira uburyo bwo gusesa - uburyo bwo gukwirakwiza: molekile ya gaze yamamajwe kuruhande rumwe rwa membrane irashonga kandi ikwirakwira muri membrane bitewe na gradient concentration, hanyuma desorb kurundi ruhande. Kuberako imyuka itandukanye ifite iseswa ritandukanye {{6} rates igipimo cyo gukwirakwiza muri membrane, gutandukanya ibice bitandukanye bya gaze birashobora kugerwaho.
